ILM shot the first Deathstar outside, so as to use the sun as a lighting source, as they had neither the stage space, nor the film speed to shoot it in a studio.
So much for that plan…
PS: Notice the wobbly plating on the walls. Somebody threathened the construction crew into finishing, and this is what they got in return. Speed, cost and quality; you can pick two out of the three…
The post-stormtrooper-visit-sandcrawler-set in its second location, a rock canyon.
The full sandcrawler set on the salt flats of Tunisia. The mound in the bottom left corner, which is the edge of the hole-in-the-ground, is just a mound though, there is no hole in the ground, that was shot at a different location altogether.
PS: A storm tore this set apart.
I’ve got nothing…
But The Making of Star Wars does (p156), which you should own if you’re reading this I might add. The Sandcrawler set, as seen here anyway - it was later moved to a canyon - was placed near the border between Tunisia and Libya, and had to be inspected by the Libyan army, who suspected it to be part of a military mobilization.
The set itself only reached a couple of meters above frame, as you can see in this photo.
Also it cost $128.000 anno 1976.
PS: No wonder ‘red’ blew a casket, check out that guy pulling all the wires out of him!
